Abstract:
The aim of this study was to identify the prognostic factors affecting recurrence and survival in patients who underwent curative intent surgery for colorectal cancer (CRC) with a single liver metastasis. Methods Between January 2006 and August 2012, we retrospectively evaluated 141 patients for CRC with single liver metastasis underwent curative intent surgery for colon and liver simultaneously. Some patients (11.3%) had radiofrequency ablation as an option. Results The 5‐year disease‐free and overall survival (OS) rates were 38.9% and 59.6%, respectively. Recurrence occurred in 77 (54.6%) patients after surgery. Multivariate analysis identified node positivity and no adjuvant chemotherapy as independent risk factors for OS. We analyzed the OS risk factors in 76 recurred patients from the time of recurrence. Multivariate analysis revealed the following significant risk factors for OS after recurrence: a high serum carcinoembryonic antigen concentration at the time of recurrence, the treatment type after recurrence (chemotherapy or no treatment) and a left hepatic metastasis. Conclusion Patients who underwent a curative resection for CRC with a single liver metastasis had a relatively favourable prognosis; in these patients, node positivity and no adjuvant chemotherapy were independent prognostic factors for OS. Furthermore, a high serum carcinoembryonic antigen concentration at the time of recurrence, the treatment type after recurrence (chemotherapy or no treatment) and a left hepatic metastasis may be independent prognostic factors for OS in patients with recurrence. The left hepatic metastasis group tended to have a multiple hepatic relapse more frequently than the right hepatic metastasis group in cases of isolated hepatic relapse.
